CA percipitation - HELP FAST!

Well, I too don't understand why you'd be getting precipitation.
How much flow is there where you add the materials?
Perhaps a kit is reading incorrectly.

You might try the nonbaked version for a while.
No, I'm not sure, but if you get precipitate, I'm also not sure why, and one possibility is that the pH is actually higher than you think. I'd try to keep the pH between 8.0 and 8.5.

That article discusses one way to do a bit of a test.
High alkalinity or high Ca can cause precipitation.

High pH is often he biggest driver, followed by high alkalinity, low magnesium, and high calcium.
I am almost positive my PH readings are correct. My magnesium tests are from a sailfert test kit, but my alkalinity and calcium tests are from a cheap "fastest" test kit. I checked the calcium kit against another I knew was accurate and it gave similar results...so the only one left Im thinking could be off is the alkalinity test kit. I should have a sailfert alkalinity test kit tomorrow or saturday...its in the mail on its way - no LFS had one.
Does anyone know of any reviews/experiences with following PH pen? http://www.drsfostersmith.com/Product/Prod_Display.cfm?pcatid=9848&N=2004+113074
Is that what you have, or are you thinking of buying it?
Does it use a two point calibration? Like pH 7 and 10 or 7 and 4?
What brand calibration fluid did you use? Some are not accurate.

OK, that should be fine then if the calibration was recent. 
AHHHHH HAAAAAAAH!!!! Got my sailfert alk test today. My DKH is at 9 - other test kit says its at 5.6! All this time it was the lame "Fastest" alkalinity kits (Bought two different ones). I took one back to the LFS and they gave me my money back...the other was too used, so I didnt bother. But yeah...Im happy as a clam now
So I was overdosing the alkalinity which percipitated the calcium.

Checked my alkalinity again...it is now 5.8 DKH according to sailfert. I did a 15 gallon water change with IO salt from DrsfosterandSmith then tested it hours after. Under these circumstances, is it normal for the DKH to go from 9 to 5.8 in a matter of 6 hours?
